Fingerprint Door Unlock System
This simple fingerprint door unlock project using Arduino can be very useful for door security, forensics, crime investigation, personal identification, attendance system and much more. In the future, there could be many more applications like fingerprint based driving licences, bank accounts operation and so on.
The whole system works under a simple algorithm called matching algorithm, which is used to compare previously-stored templates of fingerprints against users’ fingerprints for authentication purposes.
A key is normally used for traditional door opening, but it provides very poor security. In this fingerprint door unlock project, only when an authorized person places a finger on the sensor, the door unlocks and the LCD displays a welcome message along with that person’s name.
